Exploring Fungi: Life Cycles, Characteristics, and Fun Experiments

Join us for an engaging lecture on the fascinating world of fungi! We'll explore the lifecycle of slime molds, their role in decomposition, and the unique structures of various fungi, including hyphae and mycelium. Learn about the different classifications of fungi, from zygote fungi to club fungi and sac fungi, and their reproduction processes. Participate in an extra credit experiment by bringing in a food item to observe fungi growth. Make sure to read Chapter 16 in preparation for our enriching discussions!

Presentation Transcript

  1. Lecture 60 Mr. Sover 5 February 2010

  2. Check Study Guides

  3. Ch. 15 Study Guide Questions

  4. Let’s Have Some Fungal Fun! • Extra Credit (2 free quiz points) • Bring in a food in a closed container and let’s see what types of fungi grow on them!

  5. Slime Molds • Begin life cycle as a slimy mass (plasmodium) • Decomposes • Food/moisture -> scarce…then it reproduces • Slime Mold • Characteristics of both fungi and protozoans • Evolution?

  6. Slime Mold Life Cyce

  7. Kingdom Fungi • Important role in decomposing dead organisms and wastes • Release nutrients • Plant and animal-like

  8. Structure of Fungi • Hyphae (thin filaments) • No, not hyphy … • (Hyphy) • Grow out to form mycelium Specialized hyphae which form spores

  9. Fungi are classified according to the way they produce spores during sexual reproduction

  10. Zygote Fungi • Two different fungi meet… • Specialized hyphae fuse • Zygospore • Rhizoids – “root” the fungus to its food source • Rhizopus

  11. Club Fungi • Mushrooms, shelf fungi, rusts, puffballs • Contain basidia - _____________ • Each basidium produces ____________

  12. Puffball!

  13. Sac Fungi • Yeasts, cup fungi, powdery mildews • Each organism posseses a saclike stucture known as an acsus • Meiosis – spores • Lack hyphae

  14. Lichens • Fungus + Green Organism (blue-green bacteria or green alga) • Autotrophic+Heterotrophic • Harsh Environments • Creation of soil / Reindeer

  15. BBC-Fungi

  16. Homework • Make sure chapter 16 has been completely read!
